About Woolly Bluecurls (Trichostema lanatum)
62 Nurseries Carry This Plant
Add to My Plant List
Woolly Bluecurls (
Trichostema lanatum
) is named for its curled, fuzzy flowers that bloom in brilliant shades of blue and lavender. These striking flowers bloom in dense clusters on branching stems from fall to spring. A favorite of hummingbirds, the flowers also attract bees, butterflies, and other insects.
This shrub is a member of the Mint family. Its narrow, bright green leaves have a pleasant, minty fragrance. It can quickly grow to an impressive size in the first year, although as a fire-following plant, it does have a short lifespan (around 4 to 5 years).
In the garden, this plant requires specific growing conditions to do well. A young Woolly Bluecurls plant needs regular watering after planting. Once it's established, however, overwatering ? even occasional summer water ? can damage or kill them. Plant in full or part sun in light, well-draining soil. It does well in rocky areas and does not like mulch. Although short-lived, the showy blooms make this plant a stunning addition to a low-water pollinator garden.
